Q:

Do dogs have night vision?

A:

Quick Answer

Several features of dogs' eyes help them see well in the dark. Their eyes have relatively large pupils, which allows more light in and enhances night vision. The retinas, located at the back of each eye, are where images focus. Retinas have many rods, which are very responsive to light. The membranes that create eyeshine are also involved. Light that is not picked up by the rods is bounced back to the retinas by the membranes.
